SC‐550: A Sintered Calcite Reference Material for In Situ U‐Pb Geochronology

Geostandards and Geoanalytical Research, EarlyView.
Key Points New calcite reference material (SC‐550) produced by high‐temperature and high‐pressure sintering of nano‐particulate powder from a microbial limestone. Homogeneous U content (2.3 ± 0.4 μg g‐1) and U‐Pb isotope ratios (< 0.6% RSD for 207Pb/206Pb; < 3% RSD for 238U/206Pb).

Delivering Sulfate to LNAPL Body for Enhanced Source Zone Depletion (ESZD)

Groundwater Monitoring &Remediation, EarlyView.
Abstract This field pilot study evaluates the feasibility of applying sulfate to a light non‐aqueous phase liquid (LNAPL) body for achieving enhanced source zone depletion (ESZD) at a refinery site. Two rounds of gypsum land application (GLA) delivered sulfate to an 8000 ft2 area encompassing LNAPL‐containing monitoring wells MW‐2 and MW‐3, while MW‐1 ...

P‐T Uncertainty in Subsolidus Metamorphic Systems: Sources, Patterns and Controls

Journal of Metamorphic Geology, EarlyView.
ABSTRACT Phase equilibrium modelling of metamorphic rocks is subject to multiple, superimposed sources of uncertainty that affect pressure–temperature (P$$ P $$‐T$$ T $$) estimates, making it difficult to independently distinguish and evaluate the contribution of each source.

Feldspar Albitization With Implications for Reservoir Quality Evolution of Eocene Turbidite Sandstones in Offshore Espírito Santo Basin, Eastern Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT The diagenetic albitization of plagioclase and K‐feldspar grains is a transformative process that significantly alters sandstone's detrital composition and formation water chemistry, impacting reservoir quality. In this study, Eocene turbidite sandstones from the offshore Espírito Santo Basin, Brazil, were investigated to elucidate the role of

Processes and Patterns of Dolomite Precipitation in Aptian Pre‐Salt Deposits of Santos Basin, Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT The Aptian pre‐salt lacustrine carbonates represent the most significant oil exploration target along the South Atlantic margin. Dolomitization of the Santos Basin Barra Velha Formation (BVF) is critical for reservoir quality, yet its origin, patterns, and evolution remain poorly understood.

Oxygen isotope thermometry and composition of aqueous fluids within the parent body of asteroid (101955) Bennu

Meteoritics &Planetary Science, EarlyView.
Abstract We report on the petrography and oxygen isotopic compositions from in situ analyses of carbonates (Ca‐carbonate, dolomite, and Fe‐rich magnesite), magnetite, and apatite in particles from asteroid Bennu. Using oxygen isotope thermometry of Ca‐carbonate, dolomite, and magnetite, we estimated crystallization temperatures and the oxygen isotopic ...
